This is a group exercise. Each group will be given a sheet of colored paper. Turn in your answer sheet with the names of everyone in your group and the numbered and lettered answers to these questions. Discuss the material until the group exercise is over and everyone understands the concepts.

1. Your new company has been issued a class C network address. There are employees at 10 different locations. Each location has 12 people or fewer. What would be the ideal subnet mask or subnet masks so that each user could have a workstation on the internet? Explain your answer.

2. Convert the IP number 129.170.16.79 to binary. You may leave in the 3 dots to enable seeing the chunks of binary digits more easily.

3. What class of network address is the IP number 129.170.16.79?

a. Which portion of it is the network address?

b. Which portion of it is the host address?

4. Suppose the organization or university using the above network address wants to divide their network into subnets. They use the subnet mask with a 192 in it. Recall that subnet masks will be made up of 255s and 0s and possibly one other value.

a. How many subnets can they divide their organization into?

b. How many computers and printers and networked devices can they have on each one of those subnets? (Printers that have IP numbers to enable sharing over the network).

5. Suppose the same company above (with 129.170.16.79 as the address of one of the packets they received for some local host) decides to use 224 instead of 192 in its subnet mask.

a. How many subnets can they divide their organization into?

b. How many computers and printers and networked devices can they have on each one of those subnets?
